or battle till the bloody end here? >> what seems to be happening for president obama is that he has a firewall in the midwest or at least his campaign hopes that. actually, the election results come on tuesday might very well hinge on whether that firewall truly exists or not. according to our polls that you just showed in iowa, president obama has a lead. in wisconsin, it's a smaller lead. some other public polls suggest that as well. however, the romney campaign has made it adamantly clear that according to their polls in iowa, the race is dead even. so it really kind of matters where you actually see the race right now. but it's largely going to come down, as chuck pointed out, to the midwest and that's why you'll see president obama campaigning in ohio, wisconsin, iowa a lot these last five days. >> amy, let me bring you in. i know to mark's point, i believe it was one of the romney advisers or a supporter who said i think the word was "crap" when it comes to polls, at least the ones they didn't like to see. nevertheless, you can disagree with the percentage point here or there,
